Authenticating Vista to old SMB Shares
(2010-02-07 at 13:04:00)
Vista cant connetc to older SMB shares as they use the older LM authentication as opposed to newer NTLM v2 which is the default on Vista. This is actually a good thing as LM auth is a bit insecure, however it can cause problems connecting to older machines. The solution.. enable LM auth again, to do so, change the following registry key in: HKLM/System/CurrentControlCset/Control/LSA
Change the value of: LMCompatibilityLevel from its default value of 3 to 1.
Its 3 by default on Vista RC1 (NTLM2 only) and I had to change it to 1 (LM & NTLM, NTLMv2 if negotiated).
